Wine Classes in Los Angeles

I'm looking to take a good, serious Wine Class somewhere in Los Angeles. Not the valley--not the OC. I'd like for it to be a place with a beginning and hopefully advanced classes. Has anyone taken anything like this that they would recommend?

Now, I do not live on the Westside, so I can't vouch for the classes myself. However, a close friend (whose judgment I trust very strongly) took the classes with her husband and absolutely loved them. It's a class-act wine store (I've dropped in to pick up a quick bottle of Frei Bros. Cab on the way to a Westside party), I can tell you that.

I've heard great things about the wine tastings at Wally's in Westwood. They do tastings and classes fairly often, and often concentrate tastings to a particular region, which I think are fairly educational. On the web: http://www.wallywine.com/s-228-events....

Their tent sales are particularly good - and their selection of wine and spirits is always top notch.
